RESUMO
The authors made a retrospective analysis of case histories of 201 patients who had died of fatal cardiac arrhythmias. The predictors of their death were ventricular fibrillation in 133 (66.2%) patients, asystole in 68 (32.8%), electromechanical dissociation in 2 (1%). Terminal sinus tachycardia, atrial fibrillation and flutter, the second-third degree atrioventricular block, the third-fifth grade ventricular extrasystole were the most common clinical and electrocardiographic prodromes of ventricular fibrillation. In the development of the latter, various mixed disturbances of cardiac rhythm and conduction in combination with prolonged Q-T interval were of more unfavorable value. Asystole was more frequently preceded by the second-third degree atrioventricular block, complete bundle branch block, third-fifth grade ventricular extrasystole, atrial fibrillation and flutter, and various mixed disturbances of cardiac rhythm and conduction. Cardiac arrhythmias and conduction disturbance with prolonged Q-T interval were found to be precursors of asystole in 84.8%.

The authors studied the antiarrhythmic and antifibrillatory effects of the known antiarrhythmic agents and the new Soviet coronaroactive drug phenicaberan exhibiting an antiarrhythmic action. All the drugs were examined for side effects and the action on the central and intracardiac hemodynamics in patients with acute myocardial infarction. Recommendations have been given as to the choice of effective drugs for the prophylaxis of arrhythmias depending on the pattern of heart rhythm abnormality and the hemodynamics.
